Dense Radial Growth of Silver Metal Leavesin a High Magnetic Field

Abstract

Growth patterns of silver metal leaves from AgNO ₃ solutions were investigated in a high magnetic field of 8 T as experimental research of diffusion-limited aggregation (DLA) with magnetohydrodynamic drifts of ions. Silver metal leaves grew into a typical DLA form with the fractal dimension of 1.62 in the absence of magnetic fields, and they grew into a dense radial form in the field of 8 T, where the crossover in the fractal dimension from 1.69 to 2 was observed with increasing length scale.
